href

Limited availability

This feature is not Baseline because it does not work in some of the most widely-used browsers.

Non-standard: This feature is not standardized. We do not recommend using non-standard features in production, as they have limited browser support, and may change or be removed. However, they can be a suitable alternative in specific cases where no standard option exists.

The href global attribute creates a hyperlink on the MathML element pointing to the specified URL.

Example

The first equation links to the Wikipedia article about the mass-energy equivalence. The square root part of the second equation is a link to the SageMath calculation.

Note: You should avoid nesting MathML elements with the href attributes, just like elements, as is will lead to user confusion and accessibility issues.
